SPECIFICATION forming part of Letters Patent No. 370,233, datedSeptember 20. 1881I Application filed May 28, 1887, Serial No. 239,667.

To all whom it may concern.-

Be it known that I, GEORGE SERGIO BoIN, a citizen of the United States,residing at Salinas, in the county of Monterey and State of California,have invented certain new and useful Improvements in Smoking-Machines;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specication.

Figure l ofthe drawings is a side elevation of my improvedsmoking-machine. Fig. 2is top View of same. Fig. 3 is a verticaltransverse section. Fig. 4 is an end view of top a and nozzle Z. Fig. 5is a detail view of equalizenplate b. Fig. 6 is a longitudinal sectionof roller P.

This invention has relation to means for exterminating squirrels,vermin,die., by smoke; and it consists in the construction and novelcombination of parts constituting the smoking device, as hereinafter setforth.

In the accompanying drawings, the letter A designates a sheet-metal boxextending upward and provided with a fan-case or blower, B, which -isfirmly connected to the fuelbox A by the braces C C, which are attachedto the sides of the fuel-box and of the fan-case. The chute D of thefan-case tapers toward the center or the base E of the box A.

F is the wind-wheel having the shaft G, which is provided with a shaft,H, j ournaled in the opposite braces, and having au extension, K,projecting laterally. This extension is provided with an inner stop orplate, L, and is threaded at its end to engage the nut N. Before the nutN is applied a rubber roller or friction-wheel, P, is placed on theextension, and next to it a pressure-plate, R, after which the nut isapplied. By turning up the nut the rubber friction-wheel may be pressedto increase its diameter in case of wear.

T is the large drive-wheel, which is secured to the shaft S, which isjournaled in braces below the box A. This wheel is provided with asuitable handle, J, and is designed to engage the rubber wheel I. Whenit is turned, the wind-wheel will be operated, sending a blast into thebox A.

(No model.)

V V are standards,which are pivoted to the frame-work, preferably to thecurved ends of braces, as shown, and are designed to form supports onwhich the machine is rested when being worked. As these standards areindependently pivoted, they permit the box to be turned in differentdirections as the smoke formed by an intlamed composition within saidbox issues from the nozzle Z at its upper end. This nozzle is usuallyformed at the upper end of a hinged top, a, which can be opened whennecessary in turning out the ashes and dbris in cleaning the machine.

A draft-plate, b, is placed in the lower part of the box A. This plateis perforated throughout, and is applied transversely in the box abovethe base in such manner as to provide below it an air-chamber, c. Aboveit is the tire-box and fuel-chamber d. At thelevel of theequalizer-plate is the lower margin of the lower opening, e, which isprovided with a door, g, and is designed to facilitate starting thefire. Near the upper end of the box is provided a second opening. h,also having a door, k, and designed to enable the operator to introducethe fuel when needed.

NV is a handle applied at or about the middle of the machine, andadapted to facilitate carrying the same as the operator moves about fromplace to place.

Having described this invention, what I claim, and desire to secure byLetters Pat-ent, 1s-

I. The smoking-machine consisting of the upright fuel-box having hingednozzle-top,pcrforated draft-plate, and blo werattached thereto bybraces, and having its tapering chute entering the center of the base tocommunicate with the air-chamber below the equalizei1` plate,substantially as specified.

2. The smoking-machine consisting of thel upright fuel-box having upperand lower opcnings, with doors, the hinged nozzle-top, the insideperforated draft-plate, the blower attachment and its braces, and thepivoted standards, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE SERGIO BOIN.
